LM5146-Q1: Questions on the SYNCIN and SYNCOUT pins

Good morning,

Some of the older PWM control ics require a differentiated narrow pulse on their SYNC/SYNCIN pins.

1. Can I apply a 50% square wave signal to the SYNCIN pin of the LM5146 at 400kHz?

2. What is the duty cycle of the signal on the SYNCOUT pin of the LM5146?

(I need a 50% duty cycle and it will be wonderful if the SYNCOUT signal is 50% duty cycle).

I do not read anything of duty cycles regarding the SYNC pins on the datasheet.

Thank you.
